To all whom it may concern:

Beit known that I, CLARENCE E. TYLER,a citizen of theUnited States, and'resident of Specification of Letters Patent.

Newark, in thecounty of Essexand State of New Jersey, have invented certain new and useful Improvementsin, Roadway- Boxes, of whichthe followingis a specification. g I Roadway boxes heretofore in use for giving'access to.

which mains are located usually at fixed grades-undena road surface, were heretofore made of wood,- concrete, reinforced concrete or of metal, but in eithen case were difficult to assemble and to adjust 'to the varying depth, at which the mains were located undertheroad surface f a a In many cases such roadwayboxes were .made of rectangularcross section, requiring elements of-construction of a' variety of different patterns and'provided'with fastening means and interlocking means, often extending inwardly'of the roadwaybox and interfering with" the ready access to the valve locateduat the lower end thereof. I 5 The present. invention has for its purpose to provide a roadway box of circular cross section, consisting of a limited number of standard size element's, interlocked with: out the use of rods, bolts, etc.,' which elements leave the inner space of the box practically free. These elements maybe so se lected and arranged that a box of any desired height can be constructed, according to the size of the standard elements "amen:

An additional advantage of the box consists of an adjustable top, adapted for use when small variations in height, such as fractions of inches, must considered in placing the top at exactly the of the surrounding sur- The invention is illustrated in the accompanying drawings in which Figure 1, is an elevation of' the assembled roadway box, Fig. 2, a horizontal cross section in the line a-a of Fig. 1, Fig. 3, a central vertical cross section of the top frame and cover plate, Fig. 4, a perspective view of the top frame, and Fig. 5, a similar view of the base plate.

This new round roadway box comprises a base plate 1, in the shape of a circular frame,

Recesses 18 on the lower edge of the frame 13, are in engagement with the lugs 12 of theupper set of side plates and serve to position the frame on the plates.

The cover frame 19 is provided with a circular overhanging flange 20, entirely surrounding the flange 14: of the top frame 13 and acting as'an apron to lead off the rain or other water whichmight be capable of entering the box. A series of inclines 21, 22 and 23, are arranged on the frame and enga e with the corresponding inclines 15, 16 an 17, of the top frame 13, whereby the rotation of the top frame causes a vertical displacement of be efliciently utilized in, the adjustment of a substantially water proof Patented Sept.

The' excavation'for receiving a roadway box does not require to be of much larger diameter than that of the box, and the walls of the box can easily b'e'built up in this limited space without thefiuse of bolts, screws, tie rods, etc., an advantagewhich becomes ofparticular importance when'the excavation is to be made through a finished roadbed, such as one of asphalt paving or' Belgian-paving blocks.
